A FOG warning has been issued for Dorset.
The Met Office has issued a yellow warning of dense fog patches, likely to lead to some travel disruption, which is in place until 8am tomorrow morning.
Motorists have been advised to expect slower journey times and public transport users are warned that delays to bus and train services are possible.
A spokesman for the Met Office said: "Fog over parts of the south-west Midlands and West Country will thicken up during Sunday evening, whilst some dense fog patches are also expected to form early evening across south-west England and South Wales.
"The visibility will reduce to 50-100 m in places. Fog should start to thin on lower ground by the end of the night."
